Im new to the Linux Stuff an want to convert a manual Mill to CNC with the help of LinuxCNC and Mesa Cards.

Now im on the Point, where I need to control a VFD via LinuxCNC. I have a 5i20, a 7i37TA and a 7i33TA for the axis motion.
Also a SpinX1. It is possible, to connect the SpinX1 to the 7i37TA, to get the PWM, ENA and DIR Signal?
And if it is, how I would connect it?
Would like to use Out0 for PWM, Out2 for ENA and Out4 for the DIR Signal.
The 7i37 is on P3 on the 5i20.

Ok, I changed the input and output pins in the .hal from P3 to P4. That works fine.
The num_pwmgens i change from 4 to 5.
Now, how do i setup the hal to get the pwm, enable and dir signal to P3?
Can you show me an example?
